PCA1626
Key Features
- 32 kHz oscillator, amplitude regulated with excellent frequency stability
- High immunity of the oscillator to leakage currents
- Time calibration electrically programmable and reprogrammable (via EEPROM)
- A quartz crystal is the only external ponent required
- Very low current consumption; typically 170 nA
- Detector for silver-oxide or lithium battery voltage levels
- Indication for battery end-of-life PCA16xx series
- Stop function for accurate timing
- Power-on reset for fast testing
